For a certain class of signals, it is known that the recursive median filters provide a minimum of a related regularizing functional, defined by means of the l1 norm. We generalize such results, and we show that a good approximation to the minima of such a functional can be obtained, for any signal, by means of successive applications of recursive median filters of increasing order
